Originally thought of as a replacement for the wedge engines,
the "Ball Stud" Hemi was designed to be a cheap alternative to
compete with the low-cost Chevy big-blocks. They were based
on 2-bolt B-blocks, available in B and RB strokes, to make 404
and 444 cubic inch motors. The heads get Hemi chambers that
are slightly twisted and shallower than the 426 Hemi.
Here are some pictures and an excerpt from an article...






Does anyone else have any more information on these engines?
Also feel free to correct me if I am wrong with anything I stated.
